1. To guarantee top-tier performance, the permeate flow rate and stabilized salt rejection are determined under these stringently tested standard conditions:
NF membrane (2000ppm MgSO4, 0.48 MPa, 25ºC, 15% recovery), RO membrane (2000ppm NaCl solution,
1.55 MPa, 25ºC, 15% recovery) before proceeding with any hot water disinfection process.
2. Please be advised, the permeate flow may vary within a range of +/-15%, and final water yield can fluctuate further due to
the involved heat treatment process.

Farming Applications
In the quest for optimal animal health and productivity-whether for cattle, chickens, sheep, or pigs-the caliber of water holds as much significance as its availability. Ensuring superior water quality is pivotal in influencing desired growth and maximizing animal performance.
The origins of farm water can be diverse, encompassing water wells, the civil water network, and sometimes rivers or other surface sources, each with unique characteristics.
Except for the chlorine-treated civil network water, other sources often contain elevated levels of dissolved and suspended solids and pathogens. Hence, reverse osmosis technology emerges as the most efficient solution for reducing these contaminants. It is crucial for farm water, especially from non-civil sources, to undergo advanced technological treatment to reduce harmful substances, safeguarding the health and prosperity of the livestock.

ProshareRevolutionary Leap in Next-Gen Reverse Osmosis Membrane Engineering
ProshareOur team has achieved a landmark innovation by developing state-of-the-art reverse osmosis membranes. Utilizing the transformative potential of polymer interface nano-self-assembly technology, we have surmounted the common challenges in traditional membrane creation with two revolutionary advancements:
Ultra-Thin Separation Layer Innovation: With the advanced application of polymer interface nanotechnology, our team has designed a separation layer that is astonishingly three times thinner than standard polyamide thin films, which were previously limited to 100 nm. This radical reduction in thickness enhances water flux, significantly boosting permeability.
Superior Performance Enhancement: By integrating nanoparticles alongside specialized hydrophilic polymers, we have made groundbreaking progress in improving the membrane's hydrophilicity, anti-fouling properties, longevity, and resistance to oxidative damage.
When compared to traditional polyamide reverse osmosis membranes,Proshare's innovation presents breakthroughs across four critical dimensions:
Self-Assembled Nanocomposite Film Technology
By combining nano-scale precision control with nano-doping modification, we establish the foundation for ultra-thin, meticulously organized separation layers through polymer interface nanotechnology. This revolutionary technique surpasses the limitations of thickness uniformity and material diversity present in conventional polyamide membranes.
Enhanced Water Flux and Superior Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, we have precisely controlled the functional layer thickness, achieving a remarkable 3x reduction compared to traditional membranes. This strategic evolution results in >3x higher water flux and a 30% reduction in energy consumption.
Innovative Polymer Materials with Exceptional Chemical Stability
Setting a new precedent beyond polyamide, our team employs cutting-edge hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids. These advanced materials exhibit unparalleled resistance to oxidation (withstanding up to 10 ppm chlorine exposure) and superior pH tolerance (maintaining stability across the 1-12 pH spectrum).
